All correspondence must be made through the Vendor Portal. Specifications include, but are not limited to: A. Delineator Posts and Guardrail Markers (1) Tubular Delineator Posts and Guardrail Markers shall consist of a flexible, durable, and non-discoloring material that is 2 to 4 inches in diameter and resistant to ultraviolet and infrared radiation. Tubular delineator posts and guardrail markers shall be permanently closed or capped to prevent moisture or debris from entering. The upper end of the post/marker shall be flattened to provide an area at least 3 inches wide and 12 inches long to accommodate retroreflective sheeting. Posts/markers shall be white, yellow, or light gray in color. Once installed, the delineator posts and guardrail markers shall be resistant to overturning, twisting, leaning or displacement. The posts must be compatible with an anchor that holds the post in place by a locking mechanism or bolting arrangement that provides a simple method of attaching the original post, or subsequent replacement posts, to the anchor with few to no tools. Simplicity, safety and function of this postto-anchor connection will be a consideration in the award. (2) Extrusion Delineator Posts and Guardrail Markers shall consist of a single curve, C-shaped thermoplastic extrusion a minimum of 3.75 inches wide, with 0.160 inch (typical) walls, comprised of a uniformly curved profile with a 3.0” radius. All delineator posts shall be capable of sustaining a minimum of ten (10) direct wheel-over impacts at 60 MPH (100 KPH) without damage to the post or the reflective sheeting applied to the post. All posts shall be constructed of UV-stabilized thermo-plastic polycarbonate (PC) for superior durability and weathering, conforming to the following material specifications: Property ASTM Test Results Specific Gravity (typical) D 792 1.20 Hardness (min., R-scale) D 785 100 Water Absorption, 24 hours, 73 F D 570 0.576 Tensile Elongation @ break (min. %) D 638 30 % Izod Impact, 1/8” Notched, (ft. lbs./in.) D 256 12.0 Izod Impact, 1/8” Un-notched, (ft. lbs./in.) D 256 No Break Cold Temp. Impact Test (-7° F) Florida DOT Pass B. Anchors. (1) Tubular Delineator Posts and Guardrail Markers require anchors: i. Drivable Soil Anchor. The anchor for the tubular delineator post must be easily drivable in compacted gravel and durable enough to be reused in most cases as posts become damaged. Compatibility with the soil anchors presently in use will be a consideration in the award. ii. Surface Mount Anchor. The anchor for the guardrail marker must be capable of attaching to a solid horizontal surface with the use of a single bolt or lag. The surface mount anchor shall have a footprint not to exceed 20 square inches or an overall height not to exceed 2 inches. (2) Extrusion Delineator Posts and Guardrail Markers require anchors: i. Steel Anchor: The steel anchor unit shall be a hot rolled rail steel or new billet steel meeting the physical requirements of ASTM A499 and the chemical requirements of ASTM A1. The steel anchor shall be a uniform flanged channel post with nominal weight of 1.12 #/ft. (.418 kg) before holes are punched. Anchors shall be a minimum of 12” (304.5m m) in length and have a sufficient number of 3/8” (9.5 mm) diameter holes on 1” (25.38 mm) centers to facilitate attachment to flexible guide posts. Anchors shall be supplied with attachment hardware as recommended by the manufacturer. C. Color Delineator posts shall be constructed of UV-stabilized polymers and colors. The color shall be solid throughout and stabilized to resist UV degradation. Color shall be White, Yellow or Light Gray, unless otherwise specified.
